SPECIFICATION forming part of Letters Patent No. 461,364, dated October13, 1891.

Application filed April 80, 1891.

To all whom it may concern:

Be it known that we, THOMAS -MCBRIDE, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, and EBENEZER FISHER, a subject of the Queen of GreatBritain, and residing in the city of Kincardine, in the Province ofOntario and Dominion of Canada, have invented new and usefulImprovements in Spectacles; and we do hereby declare the followingto bea full, clear, and exact description of said invention, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to new and useful improvements in spectacles, itbeing the object of such improvements to provide the bridge of thespectacles with a supplemental piece which shall serve a nose-guard andprevent the bridge from cutting into the nose of the wearer by means ofbeing pivoted to "the bridge, and therefore allows oscillation on thenose.

The invention consists in providing the bridge on its under side with anoscillating arch pivoted to the lower portion of the bridge on eachside, whereby it accommodates itseltto the peculiarity of the nose,finding its own proper centcr,thus doing away with the reddening orlacerating the skin of the nose, said reddening or lacerating beingproduced by the rigidity of the spectaclebridge; and the inventionfurther consists in certain other novel features in the arrangement andconstruction of parts, all as hereinafter explained, and pointed out inthe claims.

In the accompanying drawings, forming a part of this specification,Figure 1 is a front viewof a pair of eyeglasses provided with theoscillating under arch, the said arch being shown in section to disclosethe pivots. Fig. 2 1s a perspective View of the bridge portion of theframe and the oscillating arch.

' Fig. 3 is a transverse sectional view of the bridge, taken on the linex x of Fig. 1.

Referring to the drawings by letter, A indicates the bridge forming aportion of the spectacle-frame, and is of the usual construction and maybe formed either of a rigid or flexible arch. On the under side of thesta- Serial No. 391,144. a model.)

tacles turn when beingadjusted to suit the wearer, and by reason of thiscentral axis y y the weight of the spectacles is balanced, so that whenplaced on the nose the arch b will properly adjust itself to thepeculiarity ot' the nose.

The bridge A may be formed of metal in former use. Arch 6 may be formedof celluloid, gutta-percha, aluminum, gold, or silver or othersmooth-surfaced and light material, and the same perforated, as at c, topermit a circulation of air .thereth rough.

In Fig. 2, B and A show the pivot of the lower points of the arch, whichallow the arch to oscillate and find its own center and resting place,which produces harmony, peace, and happiness to the nose.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. The combination, with the bridge of a pair of spectacles, of an underarch pivoted at its ends to the lower portion of the bridge,substantially as described, and for the purpose set forth.

2. An arch pivoted to the bridge of spectacles for the purpose ofallowing the arch to oscillate and find its own proper center andresting-place,

The combination, with the bridge of a pair of spectacles, of an underarch pivoted at its ends to the lower portion of bridge, the said underarch being perforated to admit of the circulation of air, substantiallyas described, and for the purpose set forth.

In testimony whereof we affix our signatures in presence of twosubscribing witnesses.
